Twitter has been weighing the new feature for "about a year," Bloomberg claims, and would "screen out" any keyword specified by the user, including swear words and racial slurs. Instagram introduced a similar feature for photo and video comments last month, giving people word filters and the ability to turn off comments entirely. My colleague Dana Wollman wrote an excellent piece about why these tools should have been introduced years ago -- I'm sure many feel the same way about Twitter.

The platform's public and open nature is why it's become such an important utility. But it's also fostered a community which, at times, can feel toxic and uninviting. That's dangerous, because if people feel they can't use the service without receiving an avalanche of abuse, they'll leave, diluting Twitter's user base and the amount of thoughtful, beneficial Tweets being published every day. It's a big problem for Twitter -- the company has long-struggled to explain the service's purpose, and bad press regarding celebrity departures isn't helping. To reverse its stalling user growth, Twitter needs a feature like keyword filtering, and fast.
